Abstract
A damping device is proposed, which serves to equalize and reduce pressure fluctuations arising in fuel supply systems for internal combustion engines in motor vehicles. The damping device includes a damper element which has at least one damper diaphragm fastened in a damper housing and is arranged to define a fuel chamber which communicates via a feed pipe with a fuel distributor line. The feed pipe is oriented toward a flow tube which communicates with a fuel supply line and protrudes into the fuel distributor line. The fuel chamber of the damper element communicates via a further feed pipe with the fuel distributor line. The feed pipe and the flow tube are axially spaced apart from one another by a distance (A).
